1 Claim. (Cl.'15--104.1)

This invention relates to improvements in means for cleaning the corporation cocks of various pipelines, such as for instance water mains.

The principal object of the present invention is to provide a simplified cleaning implement whereby a corporation cock or valve, after being disconnected from the users pipeline can be easily applied and the valve and adjacent passageways cleaned efiiciently and thoroughly, with but a few minutes interruption to service of the subscribers service.

Another important obiect of the invention is to provide a cleaning device for corporation cocks, which can be readily applied, employed quickly, and easily removed, and without the possibility of any interruption in the cleaning or clarification of the cock.

These and various other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawing:

Figure 1 is a side elevational view of a corporation cock and the present invention applied in conjunction with a water main, which is shown fragmentarily in section.

Figure 2 is a fragmentary sectional view taken substantially on line 22 of Figure 1 and showing other parts of the structure of Figure 1 in section.

Figure 3 is a section taken on line 33 of Figure 2.

Figure 4 is a fragmentary elevational view, looking upwardly from the line 44 of Figure 2.

Referring to the drawing wherein like numerals designate like parts, it can be seen that reference character A denotes a conventional water main which is tapped to receive a conventional corporation valve B.

The outside end of this valve B is threaded for the usual pipeline that runs into a subscribers consuming terminal (not shown), and upon this end of the corporation valve B, is mounted the present invention which is generally referred to by numeral 10.

The invention denoted by numeral 10, consists of a barrel 11, having an internally threaded hood 12 at its lower end for disposition over the threaded outlet portion of the corporation valve B.

The upper end of the barrel 11 is threaded for disposition, threadedly into a hood'13 of a coupling generally referred to by numeral 14 and the upper end of this coupling 14 is provided with a packing nut 15, through which operates slide tube 16. This tube 16 slides downwardly through the packing nut 15 and the barrel 11 and is slidable through the valve element C of the corporation valve B, when the valve C is properly positioned so that its port is aligned with the tube 16.

The lower end of the tube 16 is provided with cutting teeth 17, for cutting through any accumulation of matter located within anypart of the corporation valve B, including the port through the valve element C.

Numeral 18 denotes a T-fitting, from which a lateral arm 19 is disposed. This may be a short length of pipe, and if so, capped as at 20 to prevent any escape of water or other fluid under pressure.

Referring more particularly to the T-fitting 18, which is actually horizontally disposed, the vertical passageway thereof communicates with a short tube 21. The upper end of the short tube 21 has one end of a short ground discharge hose 22 connected thereto.

Numeral 23 denotes a ring on the barrel 11, freely slidable on the barrel, and from this extends a chain 24, which connects to a ring 25, freely slidable on the handle 19. As before stated, this handle 19 is a short length of pipe, or can be solid, if desired.

In the use and operation of this cleaning implement, generally referred to by numeral 10, it can be seen that in order to clean the valve element C and the adjacent passageways of the corporation cock B, the valve C is first rotated to close off the liberation of fiuid from the main A. After this, the usual subsoribers pipeline is disconnected from the top of the corporation cock, and the present invention denoted by numeral 11 screwed in place, with the hood 12, screwed tight over the outlet part of the corporation cock.

The tube 16 is pushed downwardly through the barrel l1 and through the port of the valve element C and with the teeth 17 any accumulation of lime deposits or other foreign substances are removed. During this operation, water from the main A, under pressure, is forcing upwardly through the tube 16 and the hose 22, will permit spilling of this onto adjacent ground.

When the corporation cock B has been sufficiently cleaned, the tube 16 is elevated and the valve element C rotated to closed position.

After this the assembly or invention 10 can be easily removed from the corporation cock and the usual subscribers pipeline attached to the outlet part of the corporation cock.

It will be observed, that the chain 24 serves not only for the purpose of maintaining the parts denoted by the tube 16 and barrel 11 connected but also to prevent the tube 16 from blowing out of the barrel 11, when the water main pressure is imposed on the cleaning assembly.

The structure 19 is employed as a handle to facilitate rotating of the assembly in order to properly screw the parts in place.

While the foregoing description sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention what is claimed as new is:

A corporation cock cleaner comprising in combination, a barrel, an internally threaded hood at the lower end of said barrel adapted to be disposed over the threaded outlet portion of a corporation cock, a coupling on the upper end of said barrel, a packing nut in said coupling, a tube slidably mounted in said barrel and extending through said packing nut, cutting teeth on the lower end of said tube, a T-fitting having one arm mounted on said tube above said coupling, a capped pipe forming a handle engaging the stem of said T-fitting, a ground discharge hose engaging the other arm of said T-fitting, a ring slidably mounted on said barrel between said hood and said coupling, a second ring freely slidable on said handle, and a chain connecting said ring.
